TANK-LUG.

SPECIFICATION forming part of Letters Patent No. 744,794, dated November24,1903.

Application at May 22, 1902.

To a, w/tom it may concern:

Be it known that I, GEORGE P. RASCK, a citizen of the United States,residing in Des Moines, county of'Polk, State'of Iowa, have inventedcertain new and useful Improvements in Tank-Lugs, of Whichthe followingis a specification.

My invention relates to band fasteners, and more particularly to thatgeneral class of fasteners which are especially adapted for use upontanks and similar articles; and it has for its object to improve andsimplify the construction of such devices; and to this end it consistsin a fastener embodying the features and arrangement of partssubstantially as hereinafter more particularly set forth.

Referring to the accompanying drawings, Figure 1 is a plan view showingthe fastener in position. Fig. 2 is a section on the line 2 2, Fig. 1.Fig. 3 is a section on the line 3 3,

Fig. 1, looking in the direction of the arrow;

and Fig. 4 is a similar section of a modified form of fastener.

My present invention is an improvement on that shown in Patent No.696,592, granted to me April 1, 1902, and embodies many features showntherein,said features being modified and adapted for use in connectionwith certain new features, as hereinafter more particularly pointed out.

Referring to the drawings, A represents a portion of a tank made up inthe present instance of wooden staves a ct a and B B represent the endsof a band of metal or similar material passing around the tank, to whichthe fasteners or lugs are attached and by means of which the bandis'tightened. Each of the'lugs O is preferably a complement of theother, and they can be used interchangeably. Each lug, preferably formedof metal, as phosphor bronze or similarmaterial, is provided with whatmay be termed a base portion 1, which in the present instanceis cutaway, leaving an opening 20, and this base portion is preferablythickened toward its center, as indicated at 21. Rising from this baseportion are the upright sides 2,and extending from these over the outerportions of the base is the inclined top portion 3, and extendinglongitudinally through the center of the top portion is a cylindricalportion 4, havlug an opening 5 for the reception of a suitthe end of theband.

able connector, (shown in the form of a bolt or rod E, having at one orboth ends a nut E.) This opening is preferably cylindrical at its outerends, and there is a cross-piece 6 be,- neath the opening, which isarranged above the base portion 1, so as'to form a longitudinal fiatslot or passage 7 for the reception of The sides of the arched portion 4extend downward, as at 8, into the 'plane of this slot and formrectangular channels on each side of the cylindrical opening, the wallsof the channels being formed by the base portion 1, the inclinedtopportion 3, the upright sides 2, and downwardly-extending sides 8. Theinclined top portion 3 extends only partially over the base portion 1and the upright sides 2, beyond the inclined top porledges 9, and theends of these ledges adjacent the top portion are preferably beveled at10. Arranged in the channels are looking devices D, shown in the form ofrectangular wedges, having a plain flat bearing-surface 11 adapted toslide in contact with the inner surface of the inclined top portion 3,and the opposite side of the wedge is preferably provided with teeth orprojections] 2 toengagethe band B. The outer portion of the rectangularwedge is cut away or reduced, as at '13, and there is a retaining devicefor holding the locking device in the rectangular channel (shownin theform of a toe or projection 14) arranged on the inclined top portion 3and adjacent the reduced portion of the-wedge, so as to engage theabutment 15 and prevent the wedge slipping out of the channel. The wedgeis preferably of greater length than the channel, so that when inoperative position it will project at each end beyond the ends of thechannel. in which it is supported and be in position to be struck by ahammer or similar tool on either end to tighten or .loosen itsengagement with the band.

In Fig. 4 I haveshown a fastener embodying the general features ofconstructionabove described, but made double, so as to permit the use oftwo bolts or rods E, and similar parts are marked the same as in theother figures, and no detailed description is necessary.

It will be seen that each lug has an arched portion for the reception ofthe bolt, and on tion, are provided with inwardlyprojecting ICO eachside thereof there is a rectangular channel for the locking devices,which are generally rectangular in shape and have a Wedgelike clampingaction to hold the end of the band in place, and when the end isinserted in the opening 5 the locking devices readily yield, but areheld from displacement in their channels and then may be secured by ablow or tap, and when once in locking position the the strain of thebands tends to cause the locking devices to more tightly engage thebands.

That I claim is- 1. In a band-fastener, a lug having a slot for thereception of the end of the band, an opening for the reception of abolt, channels one on either side of said opening, and a Wedge-shapelocking device in each channel, and of greater length than the channel,substantially as described.

2. In a band-fastener, a lug having a slot for the reception of the endof the band, a centrally-arranged opening for the reception of a bolt,channels one 011 each side of said opening, a toe controlling thechannels, and a rectangular locking device in each channel having anabutmentto cooperate with the toe, substantially as described.

3. In a band-fastener, a lug having a slot for the reception of the endof the band, a plurality of rectangular channels, and locking devices insaid channels arranged to engage the end of the band, and of greaterlength than said channels, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

GEORGE P. RASCK.
